My daughter will go to a Tokyo Metropolitan senior high school from April. Yesterday my wife wired the enrollment fee. It cost 5650 yen ($47.48 €41.85). It is much cheaper than the fee of private schools (example of one school: 355,000 yen = $3,034.19 = €2,689.39).
In addition to the enrollment fee, I have to pay other expenses by April. I will report them.
